Problem downloading a couple of modules from the Reason Course

Hi there - I recently joined the site and got two of the free reason tutorial videos. I then went and purchased the whole course but I cannot download modules 4 & 7.

I had 3 & 8 as the free ones so don’t know if this is related.

When I click module 4 it goes to download module 5 and then when I click module 5 it does a page not found error.

Similarly with Module 7 - when I click it it goes to download module 8 and clicking on moduel 8 does a page not found.

Any help much appreciated. :)
